I'd like to ask for some advice on a test recording project that I'll be very likely be tackling. I'd be recording the sound of a race car engine, specifically a Pro Formula Mazda (link) inside of a large race shop, on a machine called a dynamometer, or dyno for short. On a dyno, the car is stationary but the engine can be run at whatever revs you want. The goal of the project is to accurately capture the sound of the engine from the driver's perspective, probably in stereo but possibly in mono. The problem is this: I'd like to capture the sound of the engine, but with as little of the room as possible, as of course it's going to be a boomy, echoey mess. Ideally the dyno would be outdoors, as that would be the preferred recording environment, but that's just not logistically possible on this case. With that, am I correct in saying that a cardioid or hypercardioid would be the best type of mic to use? And also, is it even possible to minimize the sound of the 'room' in this situation? Thanks very much, Don PS First time poster and occasional lurker - but I've learned some things here, hopefully I can actually contribute at some point.
